Fire your travel agent.

I love CT and all, but as a vacation destination, absolutely not. First and foremost, I hope your girlfriend is also 21, because we have ridiculously strict drinking laws when it comes to age. She'll be left out of a ton of things if she isn't 21 as well. Second of all, CT is mostly inaccessible without a car. Our public transit is rather shite.

I just would highly suggest you go to NYC or Calirfornia or almost anywhere else, quite honestly. We're just not a "touristy" state.
